"\tSee `man strftime` for examples. These options may be used to refer to the\n"
"\tcurrent date and time. The second kind are internal to scrotty and are prefixed\n"
"\tby '$' or '\\'. The following specifiers are recognised:\n"
"\n"
"\t$i framebuffer index\n"
"\t$f image filename/pathname (ignored when used in filename-pattern)\n"

"\t$p image width multiplied by image height\n"

"\t$h image height\n"

"\t\\n expands to a new line\n"

"\t\\ expands to a literal ' ' (the string is a backslash followed by a space)\n"
